Hey,
I have developed REST API using Django REST Framework, which is used by an US Based Company Smitty LLC. And apart from this have developed APIs for many other companies as well. I feel like I might be the right person to solve your problem.
This is also because I have used Cloud Services as well like AWS EC2, AWS Lambda, AWS AppSync, AWS API Gateway etc
The problem solved will be quite helpful in terms of optimization of time and space.
Kindly consider my bid, I deliver the products on time.
Thank You
